Fahrzeugluftreifen Vehicle tires
Die Erfindung betrifft einen Fahrzeugluftreifen mit einem profilierten Laufstreifen mit durch Umfangsrillen von einander beabstandeten, über den Umfang des Reifens erstreckten Profilrippen, welche in radialer Richtung R nach außen von einer die The invention relates to a pneumatic vehicle tire with a profiled tread with spaced by circumferential grooves, over the circumference of the tire extending profile ribs which in the radial direction R outwardly from one of

Ground contact surface forming radially outer surface are limited and formed with a width B measured in the radially outer surface in the axial direction A of the tire.
Bei derartigen Fahrzeugluftreifen ist es wünschenswert zur Erzielung guter In such pneumatic vehicle tires, it is desirable to achieve good
Trockeneigenschaften und eines guten Geräuschverhaltens radial äußere Oberflächen möglichst glatt auszubilden. Bekannte Profilrillen oder Freieinschnitte beeinträchtigen die Steifigkeit und somit Trockeneigenschaften wie Traktion, Bremsen auf trockener Straße oder Handling. Darüber hinaus erleichtern sie die Entstehung unerwünschter Geräusche. Andererseits sind derartige Rillen und feinschnittfreie Profilrippen schlechter geeignet, auf nassen Straßen Wasser aufzunehmen und zu verdrängen, wodurch Nassgriffeigenschaften negativ beeinträchtigt und Aquaplaning begünstigt werden kann. Es ist bekannt, derartige Profilrippen zur Erhöhung des Nassgriffs mit Feineinschnitten auszubilden, durch welche Nassgriff verbessert werden kann. Allerdings fehlt den Dry properties and a good noise behavior radially outer surfaces as smooth as possible. Known tread grooves or free cuts affect the stiffness and thus dry properties such as traction, braking on dry roads or handling. In addition, they facilitate the formation of unwanted noise. On the other hand, such grooves and fine-cut profile ribs are less suitable for absorbing and displacing water on wet roads, as a result of which wet grip properties can be adversely affected and aquaplaning can be promoted. It is known to form such profile ribs to increase the wet grip with sipes, through which wet grip can be improved. However, the missing

Gerade bei Neureifen, in welchen das Profil mit großer Profiltiefe ausgebildet ist, können die bekannten, tief ins Profil reichenden Feineinschnitte die für gute Trockeneigenschaften gewünschte Steifigkeit unerwünscht stark herabsetzen. Der Erfindung liegt die Aufgabe zugrunde, bei derartigen Fahrzeugluftreifen trotz guten Trockeneigenschaften und gutem Geräuschverhalten einen schnelleren Griffkontakt auch auf nassen Oberflächen zu ermöglichen. Fine sipes have a capacity for quickly absorbing water on the tire surface. Especially with new tires, in which the profile is formed with great tread depth, the known, reaching deep into the profile sipes can undesirably greatly reduce the desired stiffness for good dry properties. The invention is based on the object in such a pneumatic vehicle tire despite good dry properties and good noise behavior to allow faster grip contact even on wet surfaces.
